- Your profit is the difference between what you sold for and what you paid, minus the fees on both trades.
- Exchange fees typically run from about 0.1% to over 1% per trade, depending on the platform and order type. On small trades they can wipe out a gain.
- In the US, crypto is taxed as property: gains on coins held a year or less are taxed as ordinary income, and longer-term gains at 0%, 15% or 20%.
- In the UK, gains above the annual exempt amount are subject to Capital Gains Tax at 18% or 24%, depending on your income.
How to use the crypto profit calculator
Choose your currency
Pick US dollars, pounds or euros. Use the same currency for every price you enter.
Enter your buy and sell price
Use the price per coin. To check an open position, enter today’s price as the sell price to see your unrealized gain or loss.
Enter how many coins
Fractions are fine, for example 0.25 BTC or 1.5 ETH. If you bought in several rounds, use your average buy price.
Add fees and tax
Enter your exchange’s fee per trade, plus any withdrawal or network fee and your tax rate on gains in the advanced options.
You’ll see your profit or loss after fees and tax, return on investment, total fees paid, the price change, and the break-even sell price you need just to cover your costs.
The crypto profit formula
How the calculator works it out
Cost basis = buy price × coins + buy fee
Net proceeds = sell price × coins − sell fee − withdrawal fee
Capital gain = net proceeds − cost basis
Net profit = capital gain − tax on the gain
ROI = net profit ÷ cost basis × 100
The break-even sell price is the price per coin at which the sale exactly covers your cost basis and all fees.
Worked example: selling 0.25 BTC
Buying 0.25 BTC at $60,000 and selling at $72,000
The exchange charges 0.1% on each trade and the gain is taxed at 15%.
A 20% rise in the price of Bitcoin becomes a 16.8% return after fees and tax. The break-even sell price is about $60,120, so the first $120 of any rise only covers fees.
How crypto profits are taxed
United States
The IRS treats crypto as property. Selling, swapping one coin for another or spending crypto is a taxable event. Short-term gains (held a year or less) are taxed as ordinary income; long-term gains at 0%, 15% or 20%.
United Kingdom
HMRC treats crypto as a chargeable asset. Gains above the annual exempt amount are taxed at 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers.
If you sell at a loss, that capital loss can usually be set against other gains. In the US, up to $3,000 of net capital losses a year can also be deducted from ordinary income, with the rest carried forward. Keep a record of every trade, including fees.
Tips for tracking crypto profit
Use your average cost
If you bought in several rounds, divide the total you spent (including fees) by the coins you hold to get your average buy price.
Count every fee
Trading fees, spreads, network fees and withdrawal fees all reduce your real return.
Know your break-even price
Before selling, check the price you need to beat. Small gains on small trades can turn into losses after fees.
Keep records for tax
Export your trade history from each exchange at least once a year. You’ll need dates, amounts and prices for your tax return.
Crypto profit calculator FAQ
How do I calculate crypto profit?
Multiply the sell price by the number of coins, subtract fees, then subtract what you paid (the buy price times the coins, plus the buy fee). What’s left is your profit before tax.
What is a break-even price in crypto?
It’s the sell price per coin at which you get back exactly what you spent, including all trading and withdrawal fees. Selling above it is a profit; below it is a loss.
Do I pay tax if I don’t sell my crypto?
In the US and UK, simply holding crypto that has gone up in value isn’t taxed. Tax usually applies when you sell, swap it for another coin or spend it. Staking and mining rewards are generally taxed as income when you receive them.
Is swapping one coin for another taxable?
Yes, in both the US and UK. Trading Bitcoin for Ethereum, for example, counts as disposing of the Bitcoin, so any gain on it is taxable.
Can I use this for stocks too?
Yes. The math is the same for any asset you buy and sell: enter the share price instead of the coin price and your broker’s fees.
How accurate is this calculator?
The math is exact for the numbers you enter. Your real tax bill depends on your income, allowances, holding period and local rules, so check with a tax professional before filing.
